Terra Insegura is the second book included in the omnibus edition
titled the Helix War, which also includes the first book Marseguro. I
have the separate books, but I dove right into Terra Insegura
immediately after finishing the first book. Not that the first book
ended on a cliffhanger--it was a fully resolved book--but because the
premise and the "hook" at the end of the first book demanded I read
more. *grin*
The premise is book two requires a little spoilerage of book one, so if
you haven't read that one yet, you may want to stop reading now. In
Marseguro, the genetically modified amphibious Selkies, along with
their creator Victor Hansen and a slew of unmodified humans, escaped
the persecution of the religious group the Body Unified by fleeing to a
new planet they dubbed Marseguro. They successfully hid there for 50
years, until one of the unmodified humans, Chris Keating, activated a
signal. The Body Purified attacked the unprepared planet in an attempt
to purify it of the monsters created by genetic manipulation, but the
Selkies fought back, creating a plague that kills all unmodified humans
unless they've been inoculated. In the chaos of the battles, Chris
Keating is inoculated and ends up on one of the Body Purified ships.
The plague spreads, wiping out all of the Body Purified, including
those on the ship containing Chris Keating. The only problem is, Chris
is a carrier of the plague . . . and the ship is headed back to Earth,
where the plague will wipe out humanity.
Terra Insegura begins with Richard Hanson--a clone of Victor Hansen,
with his memories implanted with a gene-bomb--and a crew of mixed
Selkies and humans from Marseguro are headed back to Earth with the inoculation in hopes of saving humanity from Chris Keating's arrival.
But what will they find when they arrive? Will the Body Purified have
contained the plague, or will it have been released on the
unsuspecting population? And if it has gotten out of containment on
the ship, how devastating will the plague be? Regardless of what's
happened, the crew from Marseguro intends to help in whatever way they
can. They never intended the plague to escape beyond their own planet.
I'll start by saying that I thought this book was much better than the
first, which I enjoyed well enough already. This second book was more
convoluted, with multiple points of view scattered to the four winds
and space beyond, all of them with their own motivations and personal
conflicts. If you recall my review of Marseguro, I emphasized the fact
that the best part of the book, for me, was the characters, and those
strong characterizations continue here. The plot was also more
convoluted and involved loyalty, betrayal, action in space, battles on
land, torture, and so many twists and turns I lost count. I wasn't
sure how to classify the first book or this one--it's not really hard
SF, nor it is military SF, although it has aspects of both. Someone
suggested it was space opera, but I didn't think it fit that
description (at least my definition of space opera) either, although
that's the closest probably. In any case, I thoroughly enjoyed this
book and would have read a third book if there was one.
So, final thought on this is that if you'd like a light military SF
novel, or a light SF novel, or perhaps a slight tweak on space opera,
then you should definitely pick up The Helix War and check it out,
keeping in mind that I think the second book is much fuller and richer
than the first.
